I just purchased goggles 2 and the motion controller 2 for my new Air 3.  When I move the motion, controller forward or back it moves the gimbal up and down instead of moving the aircraft.   could someone please help

Hi, fans192e41c4. Thank you for reaching out. Do you tilt/move the RC Motion 2 like this?

If yes, then that is normal. If you want to ascend or descend the drone, you will need to move the joystick up and down. Please refer to the video below for the complete tutorial:

Hope this helps.
